Detailed Description

The New-NetEventSession cmdlet creates a network event session. A session controls how the computer logs events and, optionally, network traffic, or packets. Later, add network event providers to a session. A network event provider logs events and network traffic as Event Tracing for Windows (ETW) events. The session stores these events in an .etl file or provides them to an application that displays them.

Assign a name for the session. Only one session can exist at a time. Remove an existing session by using the Remove-NetEventSession cmdlet. You can specify the maximum number of buffers in a session and the size of the trace buffer.

You can also specify whether to use an .etl file. If you use an .etl file, you can specify its location and maximum size. Instead of an .etl file, you can select a type of live display.

Parameters

-CaptureMode<CaptureModes>

Specifies a capture mode. The acceptable values for this parameter are:

-- SaveToFile. Saves the capture to an .etl file. -- RealtimeRPC. Connects remotely for a live event and packet capture. -- RealtimeLocal. Connects locally for a live event and packet capture.

If you specify a value of SaveToFile, you can specify a location for the file by using the LocalFilePath parameter and specify a maximum file size by using the MaxFileSize parameter.

If you specify a value of RealtimeRPC or RealtimeLocal, the capture requires additional software, such as Microsoft Message Analyzer.

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-LocalFilePath<String>

Specifies a file path. If you specify a value of SaveToFile for the CaptureMode parameter, the cmdlet saves the file to this location. Be sure that you can write to this location. If you do not specify this parameter, the cmdlet uses the default value of %LocalAppData%\Temp\NetTrace.etl.

-MaxFileSize<UInt32>

Specifies a maximum file size, in megabytes. If you specify a value of SaveToFile for the CaptureMode parameter, this value is the maximum size for the .etl file. Once the file reaches the maximum, the session continues to save events, and discards the oldest events to create space. A value of 0 means that there is no maximum. If you do not specify this parameter, the cmdlet uses a default value of 250.

-MaxNumberOfBuffers<Byte>

Specifies the maximum number of buffers used in a session. If the computer determines that the value restricts performance or the value is 0, the computer overrides the configuration to optimize trace performance.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

-TraceBufferSize<UInt32>

Specifies the amount of memory, in kilobytes, for a buffer for event tracing. The maximum value is 1024. If the computer determines that the value restricts performance or the value is 0, the computer overrides the configuration to optimize trace performance. The ETW logger uses the size of physical memory to calculate the default value.
